Barton_Choubey: Barton-Choubey criterion

In maxgav13/GMisc: Miscellaneous Functions for Geology (and its areas)

Barton-Choubey criterion

Description

Calculates the Barton-Choubey criterion for the given data and for the given level of stress (unit weight and depth).

Usage

Barton_Choubey(JRC, JCS, phi.r, unit.weight, depth)

Arguments

JRC	The Joint Roughness Coefficient (1-20)
JCS	The Joint Compressive Strength in MPa
phi.r	The residual friction angle of the rock
unit.weight	The unit weight of the rock in kN/m3
depth	The depth, in meters, to which calculate the parameters

Value

A list with 3 tibbles: data (normal stress and shear stress), stress level point, and parameters (c and phi). All stress values are in MPa

Examples

JRC = 10
JCS = 30
phi.r = 26
unit.weight = 18.6
depth = 40
